Description

本発明は、乗客を輸送する電動道路やエスカレーター等の乗客コンベアに関する。   The present invention relates to passenger conveyors such as electric roads and escalators that transport passengers.

従来の乗客コンベアにおける踏板駆動スプロケットは、上弦材や下弦材等の骨組みにより形成され長手方向へと延びる枠体に対して、直接的に固定されていた(図１，図２参照)。また、下記特許文献１には、駆動機の振動や騒音が枠体に伝わってエスカレーターの乗り心地や建物に悪影響を与えるのを防止すべく、防振ゴムを挟んで駆動機を設置する方法が記載されている。   A tread board drive sprocket in a conventional passenger conveyor is directly fixed to a frame body formed of a framework such as an upper chord material and a lower chord material and extending in the longitudinal direction (see FIGS. 1 and 2). Further, in Patent Document 1 below, there is a method of installing a drive unit with anti-vibration rubber in order to prevent the vibration and noise of the drive unit from being transmitted to the frame and adversely affecting the riding comfort of the escalator and the building. Are listed.

実開昭５８−１４７９４号のマイクロフィルム（特許請求の範囲，第１図〜第４図等）Japanese Utility Model Publication No. 58-14794 microfilm (Claims, FIGS. 1 to 4 etc.)

しかしながら、上述した特許文献１は、従来の乗客コンベアと同様に、踏板駆動スプロケットが枠体に対して直接的に固定されている。つまり、上記特許文献１は、あくまで駆動機の振動が枠体に伝わらないようにする技術であって、踏板駆動スプロケットの振動については何ら考慮されていない。そのため、踏板駆動スプロケットと踏板チェーンの噛合い及び踏板の回動に伴う振動が、踏板駆動スプロケットを介して枠体に伝わってしまう可能性がある。   However, in Patent Document 1 described above, the tread board drive sprocket is directly fixed to the frame, as in the conventional passenger conveyor. That is, the above-mentioned Patent Document 1 is a technique for preventing the vibration of the driving machine from being transmitted to the frame body, and does not take into consideration the vibration of the tread board drive sprocket. Therefore, there is a possibility that the vibration accompanying the meshing of the tread plate drive sprocket and the tread plate chain and the rotation of the tread plate is transmitted to the frame body via the tread plate drive sprocket.

特に最近では、建築基準法施行令等の改正により電動道路の運転速度の規制が緩和されたが、上述した特許文献１のような構造では、電動道路の運転速度を高速化すると、発生する振動が無視できなくなり、その振動が枠体へ伝わると乗客の乗り心地に大きな影響を与える。   Particularly recently, the regulation of the driving speed of the electric road has been relaxed by the amendment of the Building Standard Law Enforcement Ordinance, etc. However, in the structure like Patent Document 1 described above, the vibration that occurs when the driving speed of the electric road is increased. Can no longer be ignored, and when the vibration is transmitted to the frame, it has a significant effect on passenger comfort.

したがって、本発明の目的は、駆動スプロケットの振動が主枠に伝わるのを抑制し、乗り心地の良い乗客コンベアを提供することである。   Accordingly, an object of the present invention is to provide a passenger conveyor that suppresses the vibration of the drive sprocket from being transmitted to the main frame and has a good riding comfort.

上述の目的を達成するために、本発明では、長手方向両端側の上部に乗降床が設置された枠体と、この枠体内の前記乗降床下近傍に夫々軸支された一対の踏板駆動スプロケット及び踏板従動スプロケットと、これら踏板駆動スプロケットと踏板従動スプロケットの間に巻掛けられた踏板チェーンと、この踏板チェーンに連結された複数の踏板と、これら踏板と同期して循環移動する手摺を備えた乗客コンベアにおいて、前記踏板駆動スプロケットをベースに支持し、このベースを前記枠体の底部に固定した。   In order to achieve the above-described object, in the present invention, a frame having a getting-on / off floor installed at the upper part on both ends in the longitudinal direction, and a pair of tread-drive sprockets pivotally supported in the vicinity of the under-floor in the frame, Passenger with a treadle driven sprocket, a treadle chain wound between the treadle drive sprocket and the treadle driven sprocket, a plurality of treads connected to the treadle chain, and handrails that circulate in synchronization with these treads In the conveyor, the tread board drive sprocket was supported by a base, and the base was fixed to the bottom of the frame.

本発明によれば、駆動スプロケットの振動が主枠に伝わるのを抑制し、乗り心地の良い乗客コンベアを提供できる。   ADVANTAGE OF THE INVENTION According to this invention, it can suppress that the vibration of a drive sprocket is transmitted to a main frame, and can provide a passenger conveyor with favorable riding comfort.

まず、本実施例における電動道路２は、図１，図２に示す従来の電動道路と同様に、次のような構成を備えている。   First, the electric road 2 in the present embodiment has the following configuration, like the conventional electric road shown in FIGS.

乗客コンベアの一種である電動道路２は、建築建物の床面１に形成されたピット１Ｐ内に収納される枠体３で骨格が形成されており、この枠体３に主要な機器が組み込まれている。また、枠体３は、長手方向の両端側の上部に床面１と面一になる乗降床４Ａ，４Ｂが夫々設置されており、これら乗降床４Ａ，４Ｂの下方近傍に踏板駆動スプロケット５と踏板従動スプロケット６とを軸支している。   An electric road 2 which is a kind of passenger conveyor has a skeleton formed by a frame 3 housed in a pit 1P formed on a floor surface 1 of a building, and main equipment is incorporated in the frame 3. ing. In addition, the frame body 3 is provided with boarding / alighting floors 4A and 4B that are flush with the floor surface 1 at the upper ends on both ends in the longitudinal direction, respectively, and a step board drive sprocket 5 and A treadle driven sprocket 6 is pivotally supported.

ここで、踏板駆動スプロケット５は、駆動軸７上に間隔を空けて固定された一対の踏板駆動スプロケット５Ａ，５Ｂを有し、そのうち一方の踏板駆動スプロケット５Ａの幅方向内側に手摺駆動スプロケット５Ｄが、幅方向外側に動力スプロケット５Ｃが、夫々踏板駆動スプロケット５Ａと同軸に取付けられている。   Here, the tread board drive sprocket 5 has a pair of tread board drive sprockets 5A and 5B fixed on the drive shaft 7 with a space between them, and a handrail drive sprocket 5D is disposed on the inner side in the width direction of one of the tread board drive sprockets 5A. The power sprocket 5C is attached coaxially with the treadle drive sprocket 5A on the outer side in the width direction.

そして、一対の踏板駆動スプロケット５と一対の踏板従動スプロケット６の間には、無端状の踏板チェーン９が一対巻掛けられており、この一対の踏板チェーン９に複数の踏板１０が車軸を介して連結されている。これら踏板１０は、走行輪（図示せず）を有しており、この走行輪を枠体３内に敷設されたガイドレール（図示せず）に案内され、上述の２つの乗降床４Ａ，４Ｂの間を循環移動するように構成されている。また、踏板１０の両側に対向する前記枠体３には、踏板１０の移動方向に沿って欄干１１が立設されており、この欄干１１の周縁には、踏板１０と同期して循環移動する移動手摺１２が取付けられている。更に、枠体３及び欄干パネル１１Ａの内部には、移動手摺駆動機構１３が設けられているので、手摺駆動チェーン１４Ａを介して手摺駆動スプロケット５Ｄから得られた動力を、手摺チェーン１４Ｂによって移動手摺１２へ伝達できる。その結果、踏板１０の進行速度に合わせて、移動手摺１２が走行する仕組みとなっている。   A pair of endless chain chains 9 are wound between the pair of tread board drive sprockets 5 and the pair of tread board driven sprockets 6, and a plurality of tread boards 10 are disposed on the pair of tread chain chains 9 via axles. It is connected. These treads 10 have traveling wheels (not shown), and the traveling wheels are guided by guide rails (not shown) laid in the frame 3, and the above-described two getting-on / off floors 4A and 4B are provided. It is comprised so that it may move cyclically between. Further, a balustrade 11 is erected on the frame 3 facing both sides of the tread board 10 along the moving direction of the tread board 10, and circulates and moves around the periphery of the balustrade 11 in synchronization with the tread board 10. A moving handrail 12 is attached. Further, since the movable handrail drive mechanism 13 is provided inside the frame 3 and the balustrade panel 11A, the power obtained from the handrail drive sprocket 5D via the handrail drive chain 14A is transmitted by the handrail chain 14B. 12 can be transmitted. As a result, the moving handrail 12 travels in accordance with the traveling speed of the tread board 10.

一方、駆動軸７に動力を付与する手段としては、上述の動力スプロケット５Ｃを駆動させる駆動機１６が設けられており、この駆動機１６から動力スプロケット５Ｃへの動力の伝達は、駆動チェーン１５を介して行われている。尚、駆動機１６が設けられる枠体３内の空所には、電動道路２の運転を制御する電気部品や給油などの付属部品２２が内蔵されている。   On the other hand, as a means for applying power to the drive shaft 7, a drive machine 16 for driving the power sprocket 5C described above is provided, and power is transmitted from the drive machine 16 to the power sprocket 5C via the drive chain 15. Is done through. In addition, in an empty space in the frame 3 where the driving machine 16 is provided, an electrical part for controlling the operation of the electric road 2 and an accessory part 22 such as oil supply are incorporated.

次に、本実施例における特徴的な構成について、図３〜図６を用いて説明する。図３は、本発明の第１の実施例における電動道路２の枠体３内の要部を示す断面図であり、図４は、その平面図である。   Next, a characteristic configuration in the present embodiment will be described with reference to FIGS. FIG. 3 is a cross-sectional view showing the main part in the frame 3 of the electric road 2 in the first embodiment of the present invention, and FIG. 4 is a plan view thereof.

本実施例の駆動軸７の端部には、ベアリングを組み込んだ軸受８が設けられており、この軸受８をベース１７に固定することにより一体化し、踏板駆動スプロケット５Ａ，５Ｂ、手摺駆動スプロケット５Ｄ及び動力スプロケット５Ｃを、軸受８を介してベース１７で支持するように構成した。更に、このベース１７が防振材例えば防振ゴム１９を介して枠体３の底部に固定されている。また、主枠３との底部と防振ゴム１９の間には、ブラケット２０Ａが設けられており、ベース１７の高さを調整できるようになっている。   A bearing 8 incorporating a bearing is provided at the end of the drive shaft 7 of the present embodiment, and the bearing 8 is integrated by being fixed to the base 17 so as to be integrated into the tread plate driving sprockets 5A and 5B and the handrail driving sprocket 5D. The power sprocket 5 </ b> C is configured to be supported by the base 17 via the bearing 8. Further, the base 17 is fixed to the bottom of the frame 3 via a vibration isolating material such as a vibration isolating rubber 19. Further, a bracket 20A is provided between the bottom of the main frame 3 and the vibration isolating rubber 19, so that the height of the base 17 can be adjusted.

ベース１７の周囲には、調整とずれ止めを兼ねてずれ止め２１が取付けられ、位置調整後ロックナットで固定されているため、位置がずれないようになっている。尚、ずれ止め２１には、硬い防振ゴムを挟む構成としても良い。   Around the base 17, a stopper 21 is attached for both adjustment and stopper, and is fixed with a lock nut after position adjustment, so that the position is not shifted. Note that the slip stopper 21 may have a structure in which a hard vibration-proof rubber is sandwiched.

また、ベース１７のうち踏板駆動スプロケット５Ａ，５Ｂの下方に位置する部分に、踏板１０との干渉を避ける凹部１７Ａが設けられている。このため、ベース１７を設置しても、機械室の高さを深くすることなく、踏板１０を回動させることができる。尚、ベース１７の凹部１７Ａは、切欠きや開口部などにより形成されている。   A recess 17A that avoids interference with the tread plate 10 is provided in a portion of the base 17 located below the tread plate drive sprockets 5A and 5B. For this reason, even if the base 17 is installed, the tread plate 10 can be rotated without increasing the height of the machine room. The recess 17A of the base 17 is formed by a notch or an opening.

本実施例において、踏板駆動スプロケット５Ａ，５Ｂ等を枠体３へ組み込む場合は、まず、枠体３の底面にブラケット２０Ａを予めセットしておき、次に、このブラケット20Ａの上に防振ゴム１９を配置した後、この上に踏板駆動スプロケット５Ａ，５Ｂ等と一体化したベース１７を置き、更に防振ゴム１９などを挟んでボルト２３で固定する。   In the present embodiment, when incorporating the tread board drive sprockets 5A, 5B and the like into the frame body 3, first, the bracket 20A is set in advance on the bottom surface of the frame body 3, and then the vibration isolating rubber is placed on the bracket 20A. After the 19 is disposed, the base 17 integrated with the tread board drive sprockets 5A, 5B and the like is placed thereon, and further fixed with bolts 23 with the vibration isolating rubber 19 interposed therebetween.

また、従来の電動道路２の運転速度は、一般に３０ｍ／分であったが、本実施例では、建築基準法関連法規の改正により可能となった、３０ｍ／分〜５０ｍ／分の速度領域で電動道路２を運転させる。更に、従来の枠体３の深さは１０００mm程度であったが、本実施例では、枠体３の深さを７００mm以下とし、この薄型化に伴って踏板駆動スプロケット
５Ａ，５Ｂの直径を３９５mm以下とした。 Moreover, although the driving speed of the conventional electric road 2 was generally 30 m / min, in this embodiment, the speed range of 30 m / min to 50 m / min made possible by the revision of the Building Standard Law-related laws and regulations. The electric road 2 is driven. Further, the depth of the conventional frame body 3 is about 1000 mm. In this embodiment, the depth of the frame body 3 is set to 700 mm or less, and the diameter of the tread board drive sprockets 5A and 5B is reduced to 395 mm as the thickness is reduced. It was as follows.

上述のような本実施例によれば、踏板駆動スプロケット５Ａ，５Ｂと踏板チェーン９の噛合い及び踏板１０の回動に伴う振動が、踏板駆動スプロケット５Ａ，５Ｂを介して枠体３に伝わるのを抑制し、乗り心地の良い電動道路２が提供できる。また、建屋の高さ制限などによる踏板駆動スプロケット５Ａ，５Ｂの小径化すなわち機械室の薄型化や、運転速度の高速化に起因して、踏板１０に作用する遠心力が大きくなっても、踏板駆動スプロケット５Ａ，５Ｂから伝わる振動を低減できる。   According to the present embodiment as described above, the meshing between the tread plate drive sprockets 5A and 5B and the tread plate chain 9 and the vibration accompanying the rotation of the tread plate 10 are transmitted to the frame body 3 via the tread plate drive sprockets 5A and 5B. It is possible to provide the electric road 2 with a good ride comfort. Even if the centrifugal force acting on the tread 10 is increased due to a reduction in the diameter of the tread driving sprockets 5A and 5B due to the height restriction of the building, that is, a reduction in the machine room and an increase in the operating speed, Vibration transmitted from the drive sprockets 5A and 5B can be reduced.

更に、本実施例によれば、踏板駆動スプロケット５Ａ，５Ｂ等をベース１７に固定することにより、部品として置いておく場合でも転がることがなく、踏板駆動スプロケット
５Ａ，５Ｂ等に傷が付くのを防止できる。また、枠体３内に搬入する際にも、このベース１７を利用することにより、ワイヤー等で吊りながら枠体３へ直接組み込む必要がなく、安定した状態で作業ができ、作業性も良くなる。更に、電動道路２を建屋に据付けた後に踏板駆動スプロケット５Ａ，５Ｂを交換する際も、ベース１７ごとスライドさせることができるため、作業の安全性を高めることが可能である。 Furthermore, according to the present embodiment, the tread board drive sprockets 5A, 5B, etc. are fixed to the base 17 so that they do not roll even when placed as parts, and the tread board drive sprockets 5A, 5B, etc. are damaged. Can be prevented. In addition, when carrying into the frame 3, by using this base 17, it is not necessary to directly incorporate the frame 17 while suspending with a wire or the like. . Furthermore, when the treadle drive sprockets 5A and 5B are replaced after the electric road 2 is installed in the building, the entire base 17 can be slid, so that the safety of work can be improved.

また、枠体３の側部に踏板駆動スプロケット５Ａ，５Ｂ等を支持する従来の方式と比較して、本実施例のようなベース１７を介して枠体３の底部に支持する方式によれば、踏板駆動スプロケット５Ａ，５Ｂ等の左右の傾きも防止できる。更に、従来は、トラス構造で形成されている枠体３のうち縦部材に踏板駆動スプロケット５Ａ，５Ｂ等を取付けていたので、その取付け部分の枠体３に大型のＬ型鋼を用い、穴や必要に応じて切欠きを設けていたが、本実施例では、枠体３の底面部分に支持しているので、トラス構造部材を統一できる利点がある。   Further, compared to the conventional method of supporting the tread plate drive sprockets 5A, 5B, etc. on the side of the frame 3, according to the method of supporting the bottom of the frame 3 via the base 17 as in this embodiment. Further, it is possible to prevent the left and right inclination of the tread board drive sprockets 5A, 5B and the like. Furthermore, since the treadle drive sprockets 5A, 5B and the like are conventionally attached to the vertical member of the frame 3 formed of the truss structure, a large L-shaped steel is used for the frame 3 of the attachment portion, Although notches were provided as necessary, in the present embodiment, the truss structure members can be unified because they are supported on the bottom surface portion of the frame 3.

尚、本実施例では、踏板駆動スプロケット５Ａ，５Ｂをベース１７に支持する構成について説明したが、一対の踏板従動スプロケット６も同様にベースに支持しても良い。   In the present embodiment, the structure in which the tread board drive sprockets 5A and 5B are supported on the base 17 has been described. However, the pair of tread board driven sprockets 6 may be similarly supported on the base.

次に、本発明の第２の実施例について、図５及び図６を用いて説明する。図５は、本発明の第２の実施例における電動道路２の枠体３内の要部を示す断面図であり、図６は、その平面図である。   Next, a second embodiment of the present invention will be described with reference to FIGS. FIG. 5 is a sectional view showing a main part in the frame 3 of the electric road 2 in the second embodiment of the present invention, and FIG. 6 is a plan view thereof.

本実施例の踏板駆動スプロケット５Ａ，５Ｂ等は、駆動機１６のベース、すなわち駆動機１６と共通の複合ベース１８に支持されている。本実施例においても、踏板駆動スプロケット５Ａ，５Ｂ等を枠体３へ組み込む場合は、まず、枠体３の底面にブラケット２０Ｂを予めセットしておき、次に、このブラケット２０Ｂの上に防振ゴム１９を配置した後、この上に踏板駆動スプロケット５Ａ，５Ｂ等とユニット化した複合ベース１８を置き、更に防振ゴム１９などを挟んでボルト２３で固定する。また、複合ベース１８のうち踏板駆動スプロケット５Ａ，５Ｂの下方に位置する部分に、踏板１０との干渉を避ける凹部18Ａが設けられている。   The tread board drive sprockets 5 </ b> A and 5 </ b> B of the present embodiment are supported by a base of the drive machine 16, that is, a composite base 18 common to the drive machine 16. Also in this embodiment, when incorporating the tread board drive sprockets 5A, 5B and the like into the frame body 3, the bracket 20B is first set in advance on the bottom surface of the frame body 3, and then the vibration isolating is placed on the bracket 20B. After the rubber 19 is disposed, the composite base 18 unitized with the tread board drive sprockets 5A, 5B and the like is placed thereon, and further fixed with bolts 23 with the vibration isolating rubber 19 interposed therebetween. Further, a concave portion 18A that avoids interference with the tread plate 10 is provided in a portion of the composite base 18 that is located below the tread plate drive sprockets 5A and 5B.

本実施例によれば、第１の実施例と同様に、枠体３へ伝わる振動を低減でき、製作性，組立性及び保守性の優れた電動道路２を提供できる。また、踏板駆動スプロケット５Ａ，５Ｂ等と駆動機１６をユニット化しておくことで、枠体３内への組込みが容易となる。更に、複合ベース１８に、電気部品や給油部品などの付属部品を一緒に固定しておけば、枠体３内への付属部品の組込みも容易となる。   According to the present embodiment, as in the first embodiment, vibration transmitted to the frame body 3 can be reduced, and the electric road 2 excellent in manufacturability, assemblability, and maintainability can be provided. In addition, by incorporating the tread board drive sprockets 5A, 5B and the drive unit 16 into a unit, it is easy to incorporate the frame into the frame 3. Furthermore, if accessory parts such as electric parts and oil supply parts are fixed together on the composite base 18, the attachment of the accessory parts into the frame 3 can be facilitated.

尚、上述の第１，２の実施例では、踏板１０間に段差が生じない電動道路２について説明したが、エスカレーターについても同様の構成を採用することができる。したがって、本明細書中で使用した踏板という用語には、エスカレーターの踏段の意味も含むものとする。   In the first and second embodiments described above, the electric road 2 in which no step is generated between the treads 10 has been described, but the same configuration can be adopted for the escalator. Therefore, the term “tread” used in the present specification includes the meaning of the steps of the escalator.
